24 olaims.- (ci. 259-1401) regulated and further to provide a washeremploying a pair of superposed impellers which will prevent floating ofthe clothes and maintain the same within the range of action of theimpellers thus insuring eiiicient operation.

One form which my invention may assume is exemplified in the followingdescription and illustrated in the accompanying drawings, in which- Fig.1 is a vertical section of the washing machine.

Fig. y2 is a plan view in section, taken on line 2-2 of Figure 1.

Fig. 3 is a perspective view of the variable throw crank mechanismwhereby a variable stroke. oscillating movement is' transmitted to theimpellers.

Referring to the drawings in detail and particularly to'Fig. l, Aindicates a base member on which is formed a vertically disposedcylindrical ,shaped standard B, and supported by this standard is astationary tub or casing generally indicated at C. The base A and thestandard B comr prise the supporting structure of themachine.

Mounted within the tub are a pair of superposed impellers such as shownat 2 and 8 whereby movement is imparted to the water and clothes to' bewashed. An oscillating movement is transmitted to the impellers througha pair of connected driving shafts li and 5, and avariable strokeoscillating movement is in turn transmitted to the shafts through lavariable stroke crank mechanism v which is perhaps best illustrated inFig. 3. This variable stroke mechanism is'mounted in the base portionanda detailed description thereof will now be submitted: Journalled inthe base member isa vertically disposed shaft l, secured thereon is aworm gear 8, and intermeshing therewith is a driving pinion or worm- 9which is secured on a shaft I0. Mounted on this shaft are a pair ofdriving pulleys Il and i2, and adapted to drive said pulleys is a belti3 and an electric motorld. This motor is supported by a` hanger I5 andthe weight of the motor thus serves as a means for constantlymaintaining the belt i3 at the proper tension. Secured on the upper endof the Worm gear 8 is a crank pin I5 and conracted therewith is aconnecting rod I6 the function of which will hereinafter be described.Pivotally secured to ably mounted with'relation thereto.

the base member A at the point indicated at Il is an adjusting lever I8.The opposite end of this lever is supported by a pair of cross bars I9and 20. The bar 2l) .is perforated at a. number of pointsas indicated at2i, and a locking pin 22 is 5 adapted to enter one or another of theseperforations to lock the-adjusting .lever at any, point desired. Thelocking pin 22 is manually operated by a hand lever such as shown at 23,this hand lever being pivotally supported as at 24 on a post 10 25forming an extension of the lever i8. The post is also provided with arigid hand grip 25a. The grips 23 and 25a extend through a slot 26 inthe `vertical extension B and they serve the function of releasing thelocking pin 22 and of ad- 15 justing the position of the lever I8. Thelocking pin is raised by depressing the lever 23 and it is lowered byspring tension as indicated at 22a. Secured on the lower end of shaft tis a crank arml 2i. A crank pin 28. is carried on the outer 20 endthereof and this crank pin is pivotally mounted in the outer end of abar 29 which will hereinafter be referred to as the intermediate crank.A cross head member 3D engages the bar and is slid- This cross 25 headmember is supported by the adjusting lever i8 and is pivotally mountedthereon at the point indicated at 3i. One end ofthe connecting rod. i6is, as previously stated, connected with the crank pin l5. The oppositeendof the connecting rod is pivotally attached toI the cross head member3@ at the pointindicated at t2. The mechanism, consisting of the crankarm 2, the y, intermediate crank or. bar 29, thecross head 36, r theadjusting lever i8, and the connecting rod it, 3

fis'so connected that a variable throw crank cealed. Laterally extendingelements or laterally extending means fixed with respect to the'sidewalls of the base'A- and the standard B are provided for themounting oi' the gearing of the motor driven mechanism. The' 'aforesaidelements or means include a top plate D fixed with respect to thestandard B. The top plate D is provided at its center with a bearing 4afor the shaft t. This bearing is substantially coaxial with the bearingil provided for the upper end of the `shaft 5 which is connected at 5awith the shaft 4. 'I'he shafts 4 and 5 constitute shaft means for thedriving of the impellers 2 and 3.

A spider having arms E is xedly secured beneath the plate D by anysuitable means such as the bolts 4b. A bearing 4c for the shaft 4 isprovided centrally of the spider in line with the bearing da. The base Ais provided with a generally horizontal top part F integral with thebase A and the standard B and whichprovides a support for the pivot i1of the adjusting lever i8. The cross bars I9 and 20 and the motor it arealso supported from the top part F of the base A. The shaft 1 of theWorm gear 3 is journaled in a bearing 1a formed in a laterally extendingelement ib which is fixedly secured to the base A by vany suitable meanssuch as the screws 1c.

The operation of the variable throw crank mechanism will be as follows:By referring to Fig. 2 it will be noted that the adjusting lever i@assumes a position at one end ofA the supporting cross bar 2G and thatthe locking pin 22 is in engagement with .the end-most perforation 2i.

I-f it isdesired to decrease the stroke of the variable throw crank mechanism itis only necessary to depress the lever 23 and to move the adjustinglever by means of the stationary hand grip 25a so that the lockingpin'may engage one or another of the perforations indicated at 2E; thatis, the adjusting lever is swung in the direc- This movement of theadjusting lever causes the cross head 30 to slide inwardlyon theintermediate crank or bar 29 and as such decreases thestroke of theintermediate tion will be assumed when the adjusting lever I8 reachesthe point wherethe locking pin will engage the last perforationindicated at 2 ia. When this position is assumed it will be' found thatthe vpivotal connection 3| formedbetween the cross head 30 and theadjusting lever I8 will align with the end of the crank arm 21, or, inother words, the pin 28. The cross head together with the intermediatecrank 29 will then merely swing about the pivotal points 3| and 28 andno movement will be imparted to the iixed crank 21.

The mechanism so far describedrelates mere- .Ey to the driving mechanismwhereby a variable stroke oscillating movement is transmitted vto shaftsand V5. This variable stroke. mechanism is for the purpose oftransmitting van oscillating movement to the impellers 2 and 3.

These impellers in turn transmit movementto the water and clothes to bewashedI and a vdetailed description of the impellers is, therefore,

thoughtnecessary. The bottom portion of the tub is provided with acentral tubular extension generally indicated at 4|). The. upper end ofthis extension forms a bearing 4| for the shaft" .5. The upperend'ofthis shaft is provided 'with a collar 2 which rests onthebearying, and it is also-provided with a socket exof a circular disc d8. Onthe upper surface of the disc are formed a plurality of radiallydisposed vanes as indicated at 49, The central portion of the disc 48 isextended upwardly as indicated at 50 and terminates in an inwardlyturned 5 collar 5| on Whichis formed a downwardly extending hub member52. This hub member has a square opening formedtherein which fits overthe socket 43 and as both are square in shape a driving connection isalso formed between the 10 shaft and the lower impeller. The extension50 of the lower impeller is cone shape and it is considerably largerthan the tubular extension on the bottom portion of the tub. An annularintermediate chamber or space 53 is thus formed 15 into which water vispermitted to freely enter through holes or perforations such `asindicated at 5d. The lower or inner surface of the disc 48 is alsoprovided with a plurality of Vanes as shown at 55. These vanes serve thefunction of 20 circulating the water which enters the perforations 5dand of throwing it radially outwardly so that it will continuouslyescape through a small annular clearance space formed .between the outeredge of the disc |58 and the bottomfportion 25 of the tub. In otherwords, a continuous stream of. water is constantly discharging aroundthe peripheral edge of the disc 48, and this is of considerableimportance as it prevents the clothing which is being washed frombecoming wedged 30 or jammed between the bottom of the tub and theimpeller. Both impellers are removable, for` two reasons: rst, to permitready removal when cleaning and draining the tub, and, second, for thepurpose of permitting the use of either 35 impeller or both asconditions may demand. For instance, if light clothing is being washedwhich `has, a tendency to gather air and float itis only necessary touse the upper impeller. By using the upper impeller under suchconditions' the 40 clothing is maintained submerged and is'alsomaintained within the range of action of the upper impeller. If coarseand heavy clothing is being washed, it is sometimes foundfthatl it isonly necessary to use the lower impeller; and again it is found thatwhen handling certain clothing the best rsults'are obtained by usingboth impellers. To remove the impellers, it isV merely necessary toraise the cover of the tub which is indicated at 60, this cover beinghingedly secured at one peripheral edge as indicated at 6 l.` When thecover has been raised it is only necessary to grasp the-.upper impellerby 'a knob such as shown at 62 and lift it upwardly. This movement willcause the central extension 41 to 55 be removed with relation to thesocket 43. When the upper impeller has been removed it is only necessaryto grasp the cone shaped extension 50 oi the lower impeller and to liftit out vertically.

i This leaves the interior of the tub' free and open 60 indicated'at 1to make place for the impeller vanes 55. This depression also forms `anal drain chamber for the wash water, .and a. drain pipe I is thereforeconnected with the tub at this point so that 'practically speaking every70l drop ofv water may besfreely drained and removed. It will also benoted thatthe' bottom portion oiv th tub is provided with f an annularflange 12 'which projects downwardly over the vertical extension B. Theannular ange 12, is 75 provided with one or more thumb screws asthreaded opening 14 to secure the same. The annular flange 12 togetherwith thev locking means employed; to-wit, thethumb screws 13,

permits the tub as a whole to be turned about the base to assume anyposition desired. This is also important as it permits the drainconnection 1| to .be turned to a point whereA the tub can be mostconveniently drained and it also permits the tub to be turned so thatthe cover 60 will open in any direction desired. For instance, thewashing machine may be placed on the back porch or in a basement at oneend oran-l other of a set of ordinary wash trays and the cover 60 shouldtherefore swing inone direction when the washing machine is`placed atone end and in the opposite directionwhen it is placed at the oppositeend of the trays. 'I'he adjustment. of the tub here shown takes care ofsuch conditions andis for this reason important.

It also shows that means vare providedv for regulating theoscillating movement of the impellers, thuscontrolling the ve--extendingvertically from the center portion of vthe' annular recess, adriving shaft journalled within said cone shaped extension, an impellermounted in the annular depression, said impeller having acone shapedextension surrounding the cone shaped extension on the bottom ofthe tub,said impeller and its cone shaped extension being interspaced withrelation to the bottom of the tub and the vertical extension o`f thebottom to form a chamber, a driving connection formed 'between the shaftand the upper end of the impeller'extension, said impeller :beingperforated to admit water .to the space formed between the impeller andthe bottom of the tub, and means on the impeller for maintaining thewater in constant circulation through the chamber and outwardly andupwardly around the periphery of the impeller.
